Answer: Ms.Kork paid $21500 for the car.

Step-by-step explanation:

Let x represent the amount of money that Ms.Kork paid for the car.

The amount for which she sold the car was $100 more than two fifths of what she had paid for the car originally. The expression would be

2x/5 + 100

Ms.Kork sold her car for $8,700. It means that

2x/5 + 100 = 8700

2x/5 = 8700 - 100

2x/5 = 8600

Cross multiplying by 5, it becomes

2x = 8600 × 5

2x = 43000

x = 43000/2

x = $21500

Can someone help with number 20
enyata [817]

Answer:B: 36°


Step-by-step explanation:

We know that ∆ABC is isoceles, making (angle)<ABC and <BCA congruent because base angles of isoceles triangles are congruent.


Because we have parallel lines, we can look for alternate interior angle pairs. <BCA is congruent to <DAC because they're alternate interior angles.


If <BCA is x then so is <ABC.


Since triangles add up to 180° we can add all of the angles (3x+x+x) and set it equal to 180.

3x+x+x=180

5x=180

x=36


If we were looking for <BAC we would plug that back in and solve, but we're looking for <BCA which is equal to x, therefore m<BCA=36°

Which situation can be represented by the equation y = 12 x ?
Marat540 [252]

Answer:

Let's solve for x.

y=12x

Step 1: Flip the equation.

12x=y

Step 2: Divide both sides by 12.

12x /12 = y /12

x= 1 /12 y

Answer:  x= 1 /12 y

Step-by-step explanation: Hope this helps :D
